Session Log

Capture what was done in this session and append it to today's daily log at logs/YYYY-MM-DD.md. This is a personal activity log - quick, factual, and scannable - so you can rewind what you did on any given day.

Step 1: Gather context

Collect information from the session:

1. Conversation scan - what tasks were worked on, what decisions were made, what was investigated
2. Git changes - run git diff --stat and git log --oneline -10 to see what files changed and recent commits
3. Current time - use date '+%H:%M' for the entry timestamp and date '+%Y-%m-%d' for the filename

Step 2: Write the log entry

Determine the log file path: logs/YYYY-MM-DD.md (e.g., logs/2026-04-14.md).

If the file does not exist, create it with a top-level heading:

# YYYY-MM-DD

Append a new entry to the file. Each entry follows this format:

## HH:MM - Brief one-line description of the work

- What was done (2-5 bullet points, concise)
- Key files created or modified
- Related issues, PRs, or context if any

Guidelines

• Be concise - this is a rewind log, not documentation. One sentence per bullet.
• Focus on outcomes - "added webhook retry logic" not "opened file X, read line Y, discussed approach".
• Skip session mechanics - do not log "ran session-distill", "compacted context", or other meta-actions.
• Group related work - if the session had one main task, write one entry. If it had clearly separate tasks, write separate entries.
• Include blockers - if something was attempted but failed or was blocked, note it briefly.
• No em-dashes - use hyphens.

Step 3: Confirm

After writing, report the entry you added in one line. Do not read the file back.

Important notes

• Do NOT run /session-distill from here - they are independent skills and may both be triggered by the same hook.
• If the session had no meaningful work (just a quick question, no code changes, no investigation), skip silently.
• Multiple entries per day are expected - each session or compaction adds its own timestamped entry.
